The guidelines were implemented by Joe Biden’s administration last year, and they were strengthened in November to help control the spread of Omicron. On Sunday, however, travelers will no longer be required to provide evidence of a negative coronavirus test.

No longer will travelers visiting the United States be required to present proof of a negative COVID test.

The Centers for Disease Control and Prevention (CDC) announced the modification on Friday, and it went into effect on Sunday morning.

One of the few remaining government measures to control the spread of coronavirus was testing requirements for foreign visitors to the United States.

The CDC, according to a representative who spoke on the condition of anonymity, will reevaluate testing requirements every 90 days.

As it eased the restriction on non-essential travel from several European nations, China, Brazil, India, and Iran, President Joe Biden’s administration enacted testing criteria the previous year.

Initial requirements permitted fully vaccinated individuals to present a negative test within three days after travel, but unvaccinated individuals were required to present a test done within 24 hours of departure.

However, the United States observed an increase in cases related to the Omicron strain, resulting in stricter procedures requiring all travelers, regardless of vaccination status, to be tested within 24 hours of entering the country.
